RUDOLPH JOHN THIESEN AND CAMPBELL THOMAS KING, (1B,, OF ATLANTA, GEORGIA ANTISKIDDING DEVICE.

Application filed December 23, 1911.

' and C MPBnnL T. KING, Jr., citizens of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvementsin Antiskidding Devices; and We, do hereby declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and usc the same.

Our invention relates to an improved antiskid device, and it consists in the constructions, combinations, and arrangements herein described and claimed.

An object of our invention is to provide an improved anti skid device adapted to be normally locked in inoperative position and to be conveniently shifted into operative position from the drivers seat.

A further object of our invention is to provide a simple and compact device having anti-skid 'mcmbers adapted to swing over opposite sides of the tire into overlapping engagement, whereby such engagement acts to strongly brace the overlapping free ends of said members to provide a strong and rigid construction.

' In the accompanying drawings forming a part of this application and in which similar reference symbols indicate corresponding parts in the several views Figure 1 is a fragmentary View of any usual type of automobile wheel, with 'one embodiment of our invention applied thereto; Fig. 2 is an enlarged section on the line 22 of Fig. 1; Fig. 3 is an enlarged, detail, axial section through the common pivotal support of a pair of anti-skid elments; Fig. 4 is a section on the line 14 of Fig. 1; Fig. 5 isa plan viewof the chassis and running gear of a motor vehicle, with our invention applied thereto; Fig. 6 is an enlarged side elevation of the actuating means shown In Fig. 5; Fig.

7 is a det'a'il plan of the shiftable links shown in Fig. 6; Fig. 8 is an edge elevation, illustrating a modified means for attaching the wear member; Fig. 9 is a fragmentary face view of the construction shown in Fig. 8; Fig. 10 is an enlarged detail plan, illustrating a modified construction for shifting the stop into the path of the fingers, and Fig. 11 is a section on the line 11-11 of Fig. 10. s

Referring to the drawings :1 indlc'ates Specification of Letters Patent.

Serial No. 667.516.

wearing faces 7 removably attached by bolts 8, to enable convenient renewal of said faces.

loiled s1' rings 9 on the pivot 1.0 of each pair of elements are attached at their respectivcends to said pivot and elements, to provide resilient means for automatically swinging the elements of each pair from opposite sides of the tire llinto overlapping engagement on the latter; such overlapping ends of the elements acting to brace one an other for providing a strong and rigid eonst-ruction.

A latch 12 is carried by a crank 13 in position to be inserted between the two anti-skid elements of each pair for locking the latter in their inoperative position, as shown at the left'in Fig. 1; said latch being yieldingly maintained in its locking posit-ion by a spring 14 having its respective ends 16 and 17 secured to a hollow hub 15 of said crank 13 and to an car 18 on said bracket 4. A finger 19 extends laterally from each crank 13 in position for engagement by a stop, or abutment, 20 pivotally connected at 21 to a slidably mounted frame 22 and guided in a slotted block 23 for swinging said stop into and out of the path of said fingers 19 upon shifting of said frame 22.

The frame 22 is slidably mounted on the vehicle in any suitable manner, and yieldingly maintained by a spring 24 in position for retracting the stops 20 from the path of said fingers 19; a pedal 25 in position for convenient operation by the driver being connected to said frame 22 by a link 26, to provide means for readily shifting said frame against the tension of the spring 2 1 to swing the stops 20 into the path' of the fingers 19.

Figs. 8 and 9 illustrate a modified construction, in which a wear member. 27,is pivoted at 28 to the member (3, and provided with a lug 29 engaging a flat spring 30 for suchas a cable 35, operatively connects said ing into operative position on the wheel tire,

and that said elements will be resiliently pressed in overlapping engagement on said tire; thereby providing a compact and strong construction adapted for convenient and eificient use under all conditions.

We have illustrated and described preferred and satisfactory constructions, but changes could be made Within the spirit and scope of our invention.

e claim 1. In an anti-skid device for vehicle Wheels, the combination of anti-skid elements pivoted to the wheel and extending from opposite sides thereof into lapping engagement on the the tread.

2.111 an anti-skid device forv vehicle wheels, the combination of anti-skid ele ments pivoted to the wheel and provided with hinged Wear members extending from opposite sides-of the wheel intooverlapping engagement on the tire tread, and resilient means on said anti-skid elements for yieldingly resisting swing of said Wear members on their hinged connections.

In testlmony whereof, we afIiX our s1gna= tures, in presence of two wltnesses.
